The was the back wheel spinning when you did this test ?

The bike will run like crap with the airbox open anyway...


If the rear wheel is not spinning, I don't think it will activate the secondaries... Also, try revving higher than 5k .. go to about 10k and see if they work. Use a flashlight or something to make sure.

Thats what I'm trying to tell you meng...

Also, the ecu can detect a load from the sensors on the airbox ... it may never turn them on unless you are actually on the bike while moving........

Im having the same issue and have no idea what to do....the dealer doesnt "think" anything is wrong either so they are not replacing anything.

I just talked to someone at dynojet and they say that throttle position doenst matter, its all RPM controlled. The only thing that he said is that maybe they wont spray in neutral if there is a neutral cut off in the ECM but that he isnt sure of that.

You need 50% throttle opening and over a certain number of revs -->

Try 5.5k.

the only reason i know they dont work till about 10k or above is that when i put my power commander on, i stuck it on the wrong set of injectors. when i hooked the lap top computer onto the power commander i was not getting a reading for mapping, then i decided to rev the motor to see if anything changed and it did after 10 k rpms. then i called dyno jet and they told me i had it on the secondary injectors instead of the primarys

RRRRRRRRRRRRRRRR Wrong answer if you read the service manual or probably the owners manual maybe even it say 5500 RPM's or more than 50% throttle they are supposed to kick in.

What im gonna do is set up the bike on stands, put it in first and just go wide open throttle in 1st until 12K with the airbox open and see if they fire. Im gonna do it with a freind of mine so he can look at the tack and quickly engage the clutch incase god forbid the bike falls with the back tire spinning at 70 mph. My foot will be on the break and my thumb on the cut-off switch just incase. I know...not the smartest thing in the world to do but i got no choice.
